となりの怪物くん | Tonari no Kaibutsu-kun

Adapted from Ribico’s manga of the same title, Mizutani Shizuku is a smart but emotionally withdrawn high school student who sits next to ever-absent Yoshida Haru, who is known to be aggressive and intimidating. She meets him for the first time when she is tasked to visit his place and pass him school materials. She is also tasked by their homeroom teacher to persuade him to return to school or he may face expulsion due to low attendance. Despite Shizuku’s reluctance, Haru decides that they are friends as this is something that only friends will do for one another. How will their lives change with each other’s presence?

Suda Masaki as Yoshida Haru
Known to be aggressive and intimidating due to a misunderstanding with his upperclassmen, he is actually very naive and does not understand social norms. He is also academically smart, scoring top marks without having to study, and this sparks off the competitiveness in Shizuku who is the top student while Haru was absent.
